Description

[0002] In daily life, the production of various wastes, such as food waste, kitchen waste, biomass, feces (including poultry and livestock), etc., increases year by year, and the pressure on the ecological environment is also increasing.

[0003] Kitchen waste and other municipal solid waste are one of the important components of urban domestic waste. They are complex in composition, easy to rot, ferment, stink, and easily breed parasites, eggs, pathogenic microorganisms, mycotoxins and other harmful substances, which can easily cause environmental damage. They contain organic matter such as protein and oil, and have high salt content, and contain a large amount of biomass energy. Today's treatment process generally uses anaerobic digestion to treat kitchen waste and other solid wastes, which can not only reduce the amount of garbage and reduce the impact, but also produce biogas and convert waste into energy. The sludge left after anaerobic digestion of kitchen waste and other solid wastes has agricultural economic value because it is rich in humus. It is generally converted into fertilizer or soil conditioner after dehydration and composting. However, the traditional composting method, although the process is mature and simple to operate, the process often takes weeks to months, has low production efficiency and occupies a large area, and has obvious odor emission, which is easy to cause nuisance to the surrounding environment of the factory.

[0036] The present invention provides a solid waste treatment system, aiming to solve the problem that composting treatment of solid waste such as biogas residue takes a long time and occupies a large area.

[0037] Please refer to Figure 1 , Figure 2 and Figure 4 As shown, the solid waste treatment system includes a treatment chamber 1, a conveying device 2 and a drying device 3. The treatment chamber 1 has an air inlet 11, an air outlet 12, a feed port 13 and a discharge port 14. The conveying device 2 includes an input mechanism 21, a conveying mechanism 22 and an output mechanism 23. The conveying mechanism 22 includes a conveying drive and a conveying assembly 222 arranged in the treatment chamber 1. The conveying assembly 222 is arranged corresponding to the feed port 13 and the discharge port 14. The input mechanism 21 is used to input solid waste into the conveying assembly 222 through the feed port 13. The conveying drive is used to drive the conveying assembly 222 to move and drive the solid waste to move from the feed port 13 to the discharge port 14. The output mechanism 23 is used to output the material at the discharge port 14. The drying device 3 is used to introduce air into the treatment chamber 1 through the air inlet 11 to air-dry the solid waste in the treatment chamber 1.

[0038] The solid waste treatment system of the present invention treats solid waste such as biogas residue by first inputting the biogas residue through the feed port 13 to the conveying assembly 222 through the conveying mechanism, and the transmission drive member drives the conveying assembly 222 to move and transport the biogas residue to the discharge port 14, and the output mechanism 23 outputs the material at the discharge port 14, the material is the substance obtained after the solid waste treatment system treats the solid waste, when the biogas residue is in the treatment chamber 1, the drying device 3 introduces air into the treatment chamber 1 through the air inlet 11 to air-dry the solid waste in the treatment chamber 1. Compared with composting, the solid waste treatment system of the present invention can save 96% of space, and the solid waste treatment system of the present invention allows the kitchen solid waste of more than 300 tons / day using anaerobic digestion and biogas residue granulation to stay in the treatment chamber 1 for 10 hours, while the biogas residue stays in the composting tunnel during the composting process for 14 to 20 days, that is, the solid waste treatment system of the present invention takes a short time to treat solid waste and has high drying efficiency.

[0039] In addition, a temperature sensing module is arranged at the conveying component 222 near the feed port 13 and near the discharge port 14. The two temperature sensing modules can respectively sense the temperature of the solid waste. The moisture content of the solid waste near the discharge port 14 can be calculated from the temperature difference between the two temperatures. Once the moisture content reaches the set value, the set value can be set to 30%, 35%, 40%, etc., and the conveying drive member drives the conveying component 222 to move so that the sludge reaches the discharge port 14. The speed and movement time of the conveying drive member driving the conveying component 222 to move can be controlled, thereby optimizing the treatment of solid waste.

[0040] It should be noted that the solid waste treated by the solid waste treatment system of the present invention may come from a centrifuge, and the centrifuge first dehydrates the solid waste.

[0041] Please combine Figure 1 and Figure 3As shown, in one embodiment, the input mechanism 21 includes a first conveyor 211 and a distributor, and the solid waste treatment system also includes a feed bin 4. The inclined bottom end of the first conveyor 211 is connected to the feed bin 4, the first conveyor 211 is inclined, and the inclined top end of the first conveyor 211 is located above the distributor. The distributor is arranged close to the feed port 13. The first conveyor 211 is used to transport the solid waste in the feed bin 4 to the distributor, and the distributor is used to input the solid waste through the feed port 13 to the conveying component 222. The first conveyor 211 can be a screw conveyor. The solid waste is conveyed from the feed bin 4 to the distributor by the first conveyor 211. The distributor distributes the solid waste to the feed port 13 of the treatment chamber 1. A rotary screw conveyor is provided at the feed port 13. The rotary screw conveyor evenly lays the solid waste at the feed port 13 on the mobile conveying assembly 222. The laying thickness can be set according to actual requirements, such as 100mm, 120mm, 150mm, 170mm, etc. While waiting for the solid waste to be air-dried, the centrifuge can continue to operate, because the capacity of the feed bin 4 can be set to 40m³, and the feed bin 4 is used to store the solid waste. The capacity of the feed bin 4 is 40m³, and it can be stored for 10 hours under full-load production.

[0042] Furthermore, the distributor includes a feed hopper and a bidirectional conveyor. The inclined top of the first conveyor 211 is located above the feed hopper. The first conveyor 211 is used to transport the solid waste in the feed bin 4 to the feed hopper. The bidirectional conveyor is connected to the feed hopper. The bidirectional conveyor is used to input the solid waste in the feed hopper to the conveying component 222 through the feed port 13. The first conveyor 211 transports the solid waste to the feed hopper. When facing two treatment chambers 1, the distribution can be carried out by the bidirectional conveyor. The bidirectional conveyor can transport the solid waste in the feed hopper to two directions that are away from each other. The feed ports 13 of the two treatment chambers 1 are arranged at intervals along the conveying direction of the bidirectional conveyor. The bidirectional conveyor rotates forward to transport the solid waste in the feed hopper to the feed port 13 of one of the treatment chambers 1. The bidirectional conveyor reverses to transport the solid waste in the feed hopper to the feed port 13 of the other treatment chamber 1. Similarly, the number of distributors can be determined according to the number of treatment chambers 1. A distributor can be arranged between each two adjacent treatment chambers 1.

[0043] In addition, please combine Figure 2 and Figure 3As shown, in one embodiment, the output mechanism 23 includes a second conveyor 231 arranged obliquely, and the solid waste treatment system also includes a storage bin 5 arranged above the feed bin 4. The inclined bottom end of the second conveyor 231 is connected to the discharge port 14, and the inclined top end of the second conveyor 231 is connected to the storage bin 5. The second conveyor 231 is used to output the material at the discharge port 14 to the storage bin 5. When the solid waste in the treatment chamber 1 is air-dried to meet the requirements, the conveying component 222 conveys the air-dried solid waste to the bottom platform, and a scraper is provided at the bottom platform. The scraper scrapes the solid waste on the bottom platform to the discharge port 14, and the second conveyor 231 conveys the material at the discharge port 14 to the storage bin 5.

[0044] In another embodiment, please combine Figure 2 As shown, the output mechanism 23 also includes a rotary conveyor 232, the inlet of the rotary conveyor 232 is connected to the discharge port 14, and the outlet of the rotary conveyor 232 is connected to the first conveyor 211. The rotary conveyor 232 is used to output part of the material at the discharge port 14 to the first conveyor 211. After the biogas residue is air-dried, it forms final particles. A part of the final particles can be transported to the first conveyor 211 through the rotary conveyor 232. The final particles are mixed with the solid waste in the first conveyor 211, and then transported to the conveying assembly 222 in the treatment chamber 1 through the feed port 13 by the first conveyor 211, so as to further optimize the evaporation process. Another part that has not been mixed back is directly transported to the storage bin 5 through the second conveyor 231.

[0045] Please combine Figure 3 As shown, the bottom of the feed bin 4 is provided with a distribution mechanism and an in-bin conveyor, and the distribution mechanism includes a distribution drive and a distribution frame, and the distribution drive is used to drive the distribution frame to move and distribute the solid waste in the feed bin 4 to the in-bin conveyor, and the in-bin conveyor is used to convey the solid waste to the connecting position between the feed bin 4 and the inclined bottom end of the first conveyor 211. When it is necessary to convey the solid waste in the feed bin 4 to the inclined bottom end of the first conveyor 211, the distribution drive at the bottom of the feed bin 4 drives the distribution frame to move, and the distribution frame can distribute the solid waste in the feed bin 4 to the in-bin conveyor, and the in-bin conveyor conveys the solid waste to the entrance of the first conveyor 211. Among them, the distribution drive can be driven by hydraulic pressure.

[0046] It should be noted that the unloading principle in the storage bin 5 is the same as that in the feed bin 4, and is also realized through the distribution mechanism in the storage bin 5 and the conveyor in the cabin, which will not be repeated here.

[0047] Furthermore, please combine Figure 4 and Figure 5As shown, in order to achieve multiple functions, the conveying assembly 222 includes a conveyor belt 2221 and two rotating shafts 2222 arranged at intervals. The conveyor belt 2221 is arranged around the outer circumference of the two rotating shafts 2222. The conveying drive is used to drive any one of the rotating shafts 2222 to rotate and drive the conveyor belt 2221 to move, and drive the solid waste to move from the feed port 13 to the discharge port 14. When it is necessary to convey solid waste, the conveying drive drives one of the rotating shafts 2222 to rotate and drive the conveyor belt 2221 to move, thereby driving the solid waste on the conveyor belt 2221 to move, so that the solid waste can be moved from the feed port 13 to the discharge port 14. In this process, the drying device 3 can air-dry the solid waste.

[0048] In addition, in the above-mentioned embodiment, a plurality of conveying plates 2223 for holding solid waste are sequentially provided on the conveyor belt 2221, and each conveying plate 2223 is rotatably provided on the conveyor belt 2221. The conveying mechanism 22 includes a shifting assembly, and the shifting assembly includes a first shifting block and a second shifting block. The upper and lower ends of the conveyor belt 2221 are respectively provided with a first shifting block and a second shifting block. The first shifting block is used to shift the conveying plate 2223 to a first state, and the second shifting block is used to shift the conveying plate 2223 to a second state. Conveyor plates 2223 are sequentially arranged on the conveyor belt 2221, and the conveyor belt 2221 is provided with two chains arranged around the outer periphery of the rotating shaft 2222, and the two chains are arranged at intervals. Both ends of the conveyor plate 2223 are rotatably connected with the two chains respectively, and both ends of the conveyor plate 2223 are provided with abutment blocks abutting the two chains. The first shifting block shifts the conveyor plate 2223 so that the abutment block abuts against the chain. At this time, the conveyor plate 2223 is in a first state, and the conveyor plate 2223 can be used to hold solid waste. The second shifting block shifts the conveyor plate 2223 so that the abutment block is disengaged from the abutment with the chain. At this time, the conveyor plate 2223 is in a second state, and the conveyor plate 2223 will flip over and sprinkle the solid waste, and fall onto the conveyor plate 2223 of the next layer. In one embodiment, 3 to 10 conveyor plates 2223 are filled with solid waste in one batch, the length of each conveyor plate 2223 can be set to 300 mm, and a groove for holding solid waste can be set on the conveyor plate 2223, and the depth of the groove can be set to 100 mm to 200 mm, such as 100 mm, 120 mm, 150 mm, 160 mm, 180 mm, etc. The conveyor plate 2223 moves forward in the process of being filled with solid waste, and then stops moving during the waiting time, and continues to move after the solid waste is air-dried, until the air-dried solid waste is transported to the discharge port 14. Moreover, in one embodiment, in order to increase the life of the conveyor plate 2223 and prevent the conveyor plate 2223 from being corroded, the conveyor plate 2223 of the granulator is made of perforated low-carbon steel with a powder coating.

[0049] In one embodiment, the number of the conveying components 222 is at least two, and at least two conveying components 222 are arranged in sequence from top to bottom.

The three conveying components 222 are arranged in sequence from top to bottom to form six conveying layers, and each layer is provided with a first shifting block and a second shifting block. The top conveying layer is covered with dehydration digestion liquid by the dosing screw. When the solid waste is spread on the top conveying layer, it can be quickly dehydrated under the action of the dehydration digestion liquid. Moreover, the solid waste can be sprinkled on the lower conveying layer through the second shifting block. When each layer receives solid waste, the conveying plate 2223 of the layer is shifted by the first shifting block and is in the first state. When each layer sprinkles solid waste, the conveying plate 2223 of the layer is shifted by the second shifting block and is in the second state. This process is repeated until the solid waste is discharged from the bottom of the bottom conveying layer.

[0050] Furthermore, please combine Figure 4 and Figure 5 As shown, the solid waste treatment system also includes a crushing device 6, which includes a crushing drive and a crushing member 62 located above the conveying assembly 222. The crushing drive is used to drive the crushing member 62 to crush the solid waste on the conveying assembly 222.

The crushing member 62 is located above the top conveying layer, and the crushing drive drives the crushing member 62 to crush the agglomerates in the solid waste, thereby expanding the surface area of ​​the solid waste exposed to the hot air. The crushing member 62 can be a rod-shaped structure, and a crushing protrusion for crushing the solid waste is provided on the crushing member 62 along its radial direction. The extension direction of the crushing member 62 can be consistent with the movement direction of the transmission assembly. It should be noted that the crushing member 62 can also be arranged above each layer of the conveying layer, thereby further expanding the exposed surface area of ​​the solid waste.

[0051] In addition, please combine Figure 1 and Figure 2As shown, in one embodiment, the processing chamber 1 includes a granulation zone 15, an air inlet zone 16 and an air outlet zone 17, the air inlet zone 16 and the air outlet zone 17 are respectively arranged on both sides of the granulation zone 15 and are both connected to the granulation zone 15, the air inlet zone 16 has an air inlet 11, the air outlet zone 17 has an air outlet 12, the granulation zone 15 has a feed port 13 and a feed port 14, and the drying device 3 includes an air supply mechanism 31 and a heating mechanism 32, the air supply mechanism 31 is used to draw air into the air inlet zone 16 through the air inlet 11, and the heating mechanism 32 is used to heat the air entering the air inlet zone 16 through the air inlet 11.

A heating mechanism 32 is also provided at each air inlet 11. The heating mechanism 32 can be a heat exchanger. The main heating pipe of the heat exchanger is passed with hot water or steam, and the air passes through the outside of the main heating pipe and is heated. The heat exchanger heats the incoming air, so that the air entering the granulation area 15 is hot air, which accelerates the evaporation of water of the solid waste on the conveying assembly 222 in the granulation area 15. It should be noted that a part of the air supply mechanism 31 can also be set to recycle the air in the processing chamber 1 to save resource consumption. Specifically, the air used for the drying process comes directly from the granulation area 15 and comes from the air outlet area 17 through the pipeline system. It is sucked into the granulation area 15 through a series of heat exchangers. The hot water in the heat exchanger flows through the main heating pipe. In the air flow through the granulator, up to 50% of the air is recycled to maximize the use of existing heat. In addition, it should be noted that the exhaust gas discharged through the exhaust area 17 is sent to the central air pollution control system, and harmful pollutants are treated and neutralized before being discharged into the atmosphere.
